20. To start the sampling routine with the first bottle, accept the blinking "1" by pressing the
you want to start the routine with another bottle, enter the starting bottle number here.
This display appears as the sampler counts down the time remaining to the start time. The first line reports the bottle
which will receive the next sample volume. The second line reports the start time at the left and the current time on
the right.
When the start time arrives, the sampler will take the first sample. The sample event cycle begins with a pre-sample
purge. During the purge, the display indicates the bottle number which will receive the sample volume.
As soon as the pump runs forward to deliver the sample volume, the message on the second line appears. This
message remains through the post-sample purge.
This display appears when the post-sample purge from the previous sample event is completed. It indicates the bottle
number which is to receive the sample at the upcoming sample event. The second line displays the scheduled time
for the next event on the left. The current time is displayed on the right.
The cycle of displays is repeated for each bottle until the sampling routine is done.
When the routine is completed, this message appears. It reports the status of the routine ("DONE"), the total number
of sample events, and the current time and date.

Example Storm Sampling illustrates how to program a 24-bottle
sampler to allocate six bottles to the first bottle group. The
remaining 18 bottles, allocated to the second bottle group, will be
used for flow-weighted samples. The sampler delays the first
group 25 minutes after it is enabled.
For the first bottle group, the sampler will take two samples with
a 5-minute interval between each sample event. At the first
sample event, bottles 1 through 3 will each receive 900 ml each
(bottles-per-sample multiplexing). At the second timed event,
bottles 4 through 6 will receive 900 ml each.
The sampler will fill the second bottle group with flow-paced
samples during the same time as the second bottle group. At each
sample event, a single bottle in the second bottle group will
receive a 400 ml sample. Each bottle will receive samples from
two sample events (samples-per-bottle multiplexing).
